The only law in Georgia is that you can't knowingly sell a firearm to a felon. Guns are not registered in Georgia and you do not have to have a bill of sale. Having a BOS is good to have if you unknowingly buy a stolen gun.
Smart folks require a peak at a valid CCW.
Please feel free to correct me if I'm wrong. I won't get upset or act like a victim.
How can you tell that you're peeking at a 'valid' GA Weapons Carry License?
How does that protect you if the buyer has committed a felony but never turned in his GWCL?
